JOHN COXEN, OF SAN FRANCISCO, CALIFORNIA.

STATION-INDICATOR.

SPECIFICATION forming part of Letters Patent No. 262,932, dated August22,-1882.

Application filed May 26, 1882. (No model.)

T 0 all whom it may concern:

Be it-known that I, JOHN COXEN, a subject ofthe Queen of Great Britain,and residing at San Francisco, inthe county of San Francisco and Stateof California, have invented certain new and useful Improvements inStation -Iudicators, of which the following is a specification.

My invention relates to certain improvements in that class of stationindicators or calendars that are operated by the axles of the ear; and

. it consists of a ribbon or map which unrolls as the car proceeds andexposes the names of streets, roads, or stations in their consecutiveorder from a slit or opening as the train or car approaches a station.The said map of the route or list of streets or stations is wound andunwound from a pair of rollers which receive motion from one'ot' thecar-axles; and the object of my improvement is to provide a street orstation indicator operated in an automatic manner by a directbelt-connection with the revolving axle, and having its ribboncarryingrollers so constructed and arranged as to move at an unequal rate ofspeed to wind or unwind the said ribbon or band and indicate the name ofthe various stations as the car advances upon the road, either toward orfrom a given point. I attain this object by the mechanism illustrated inthe accompanyin g drawings, in which- Figure 1- is a plan view of myimproved station-indicator. Fig.2 is a sideelevation thereof. 'Fig. 3isa perspective view of the ribboncarrying rollers. Fig. 4 is aperspective view of the spring-clip. Figs.5 and 6 are plan andsideelevation views illustrating a modification.

Similar letters of reference are used to indicate like parts throughoutthe several views.

Upon one of the axles, A, of the car I place a chain-wheel, B, overwhich is passed a chain, G, connecting with a large chain-wheel, D,keyed upon a shaft, E, mounted in suitable bearings, F F. The shaft Ehas keyed upon it the pinion Gr, havingcog-teeth upon its face, andinterior bevel-teeth which engage with an intermediatetransversely-journaled pinion, H,

meshing with the loosely-journaled pinion I, and imparting to it areversemotion from that had by the shaft E, upon which it freely turns.

The spur-teeth of the wheels G I mesh with the teeth of the cog-wheel J,keyed upon a shaft, K, which is adapted to he slid back and forth in itsbearing, so as to engage with either one of the gear-wheels G I, and isheld in such position by a spring-clip, L, which fits within a slot madein one of the bearings and enters an annular groove on the shaft K. Theshaft K also carries the mutilated cog-wheel M, which meshes with thespur-wheel N, upon the end of whose shat'tis afianged band-wheel, 0,over which is passed an elastic endless hand or belting, P, which is ledup over suitable friction or guide pulleys to the rollers Q It, suitablyjournaled and carrying the indicating-ribbon S. These rollers areflanged at either end, and have also an intermediate bon that theelastic driving-belt]? passes, as i will be seen upon reference to Fig.3.

The operation of my improved station-indicator will be as follows, towit: The gearwheel J having been thrown into contact with thepinion Gand the car started,a revolution of all the connected gearingwill be hadand the rollers Q S operated, and the indicatingribbon will be unwoundfrom one roller and wound upon the other; but when the teeth of themutilated cog-wheel M pass out of gear with the spur-wheel N theindicating-ribbon will remain stationary and exhibit the name of thestation. When the end of the road is reached and the car about to starton its return-trip the spur-wheel J is slipped into gear.

with the pinion I and a reverse movement is imparted to the rollers andindicating-ribbon P, by passing over it, causes the rollers to performan unequal number of revolutions in a given time, and thus wind up theribbon on one roller as fast as it unwinds from the other roller, andboth ribbons travel in the same direction and at the same rate of speed.

In the modification shown in Figs. 5 and 6 an endless belt, Y, having alug upon its outer face, passes over and is driven by the axle of thewheel J and over a roller, W, placed in close connection to the trundleor star-pinion X,meshing with the spur-wheelN, which drives the elasticbelt 1?. Bythis construction it Will i be seen that an intermediaterotary motion is imparted to the pinion X by the lug on the belt Yengaging with it and moving itthe distance of onetooth at a time. Thismodification will be found useful when thestations are a long distanceapart.

The gearing, rollers, &c., may be placed in any convenient positionwithin or upon the car and inclosed in a suitable casing.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 18-

In a station-indicator, the combination, with a rotating car-axle, ofthe chain or belt 0, chain wheel B, externally and internally toothedpinions G I, transverse pinion H, spurwheel J, having on its shaftthemutilated pinion M, meshing with the spur-wheel N on the shaft of aband-Wheel, O, the elastic belting P, and rollers Q R, carrying anindicatingribbon, S, constructed, arranged, and operating substantiallyin the manner and for the purpose herein set forth and specified.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 28th day of April, 1882.
